Describe three systems development tools and three development methods.

Program Plan Intro

Description of three tools and methods for system development.

Program Explanation

Three tools used in system development are modeling, prototyping and Computer Aided system engineering are:

Modeling: Modeling gives a graphical representation of the system that the developers can test, analyze and modify. A System analyst uses a set of business, network, object, data and process model to describe and simplify information system.

Prototyping: Prototyping performs test on system concepts and examines input, output and interfaces before reaching at a final decision. Prototype is considered as the initial model which is tested and is used to evaluate the final model.

Computer Aided system engineering (CASE): It is a powerful tool used by the system analysts to develop and maintain the information system. It provides different methodologies for system development like object-oriented analysis and structured analysis...
